Please add more context on the AMLRequest and AMLResponse classes

Bắt đầu với các trang tham chiếu về AMLRequest và AMLResponse cùng tệp nguồn AzureML-Docset/stable/docs-ref-autogen/azureml.contrib.services.aml_request.AMLRequest.yml; so sánh chúng với mẫu online-endpoints-binary-payloads.ipynb được liên kết. Ghi lại các tham số, thuộc tính liên quan và cách sử dụng mẫu để truyền JSON cùng với một tệp nhị phân và truy cập tệp đó trong scoring script.

I am testing the sample https://github.com/Azure/azureml-examples/blob/main/sdk/python/endpoints/online/managed/online-endpoints-binary-payloads.ipynb
As per the documentation, the AMLRequest and AMLResponse classes were inherited from flask.wrappers. However, please also add the parameters and attributes and sample usage of these classes.

If I am sending a JSON object to the MOE (Managed Online Endpoint) along with the binary image file, the request object will hold these values passed as raw httprequest.

payload = {"file-metadata": {
    "filename": "my-image.jpg",
    "file-size": "150kb",
    ...
}}
res = requests.post(
    url=scoring_uri,
    headers={"Authorization": f"Bearer {key}"},
    json=payload, **attempt to pass the payload to the request**
    files=[
        ("file", open("my-image.jpg", "rb"))
    ],
)

How to pass a JSON payload to this request and access that from within the scoring script? I tried to configure the json parameter to assign a sample JSON payload as above sample. However, when viewing the value through req.get_json() in the scoring script, this function returns empty.

@rawhttp
def run(req : AMLRequest):
    print(req.get_json()) **nothing gets printed out**

I found a workaround to assign the payload to the headers parameter as follows. However, it would be appreciated if you may also include the correct approach/sample usage of the above class(es).

payload = {"file-metadata": {
    "filename": "my-image.jpg",
    "file-size": "150kb",
    ...
}}

headers_ = {"Authorization": f"Bearer {key}", "File-Metadata": json.dumps(payload)}

res = requests.post(
    url=scoring_uri,
    headers=headers_
    ...)
